How to convert TRASH PLASTIC into a MESH TRASH BAG MATERIAL for plastering with cement ? Help avoid disaster! Answered


To eliminate our plastic trash problem, I would put it all into "trash rocks" and build with it.  Right now, my source of used fishnet left the island, so my source dried up. 

Best would be to not rely on finding used material, but rather to convert some of the same waste plastic into the mesh material that will contain the rest of the waste material.  Ideal, would be to have it already shaped into trash sacks for people, so that they only have to fill them and plaster them with cement. 

Anyone who can figure this one out might help the world out a lot in eliminating all the waste plastic that is contaminating land and sea these days.  I imagine maybe melting down some of it and extruding it into lines that would fuse together over a trash sack size mold. 

Figure out a safe way to do that and you could possibly have a very marketable product.  Everyone agrees that the trash plastic is a problem, and we are not recycling it fast enough to keep up with with the growing pile.  Plasterable trash sacks could help solve that problem. 

You would probably need some chemistry background for this.

I've stuck thick plastic bags into a paper shreder and it turned it into a mesh like product

I picture something more like a pile of confetti. I suspect it wouldn't work well as a fishnet substitute.

Cement doesn't stick well to some plastics, such as polyethylene. It is best to depend more on the cement getting around the fibers and mechanically locking onto them.

Cement doesn't stick as well to a woven plastic feed sack, where it can't penetrate the weave as easily as it can with fishnet.
